Assess the pelvis and thigh position carefully and evaluate if the user can tolerate corrections. Fine-tuning the angles can have a positive impact on the alignment of the trunk and spine, use the 3A back angle adjustments and the back straps to assess the desired sitting angles.

Seat: The thigh position is important for stability and upper body balance. Use an adjustable seat cushion or create a shape with additional cell foam wedges (1,2) that can be attached under the cushion cover directly to the foam. Pelvic obliquity can be accommodated with the Large Cell Foam Wedge (3).

Back Support: The 3D Back cushion (4) contours perfectly to the user's back, and the tension adjustable back straps stabilize and support the trunk.

Trunk Support: The trunk may need lateral support (5). They should be positioned higher on the side the person is leaning to and counteract further down on the opposite side.

Positioning Belt: Use a positioning belt (6) if the user has sliding problems.
Arm Support: If the user is leaning towards the arm support, make sure the height is appropriate and choose the arm support with a wide and soft plate, maybe with a soft cover (7)? In some cases, the arm supports may be set with different heights.

Tray (8): Support from the front can help the user to better trunk symmetry.

A too-upright position may trigger lateral flexion. Secure the active seat tilt with the Comfort Tilt Lock (9) and the active back support position with the Back Angle Control (10).

9. Comfort Tilt Lock

This function ensures the same preset tilt position. There are four alternative settings (0°, 4°, 8° or 12°). Choose one position that is frequently used, for activity or rest. Not in combination with Etac Prio electrical tilt.

10. Back Angle Control

Limits the back angle forward on the Prio for an active seat position. By adjusting the length of the strap, the active back support setting can be controlled. The back will always stop at the preset angle.

11. Pressure distributor

The pressure distributors could be used instead of the short plush wedge to spread the load, to give extra comfort where needed to avoid peak pressure and to create a wider back for support behind the higher shoulder.
